I missed that silicon; mine was 5. If I remember correctly the silicon can also be from sealant used for assembly. But I would certainly check the intake system as you mentioned.
I didn't do the 1200 miles change oil report but that could be an interesting one. Hopefully the wear metal stuff is small enough to not affect the wear. Sand certainly could cause wear.

Looking at the high silicon value - time to check the tightness of intake trunking downstream of the air filter, and maybe the seating of the filter itself.
